Added Docker build files

Added Docker support 😃

[atauenis]

I'm don't see ability how to provide custom configuration files into the image, like able in https://github.com/way5/docker-webone .

[nefarius]

Indeed, maybe @way5 should just PR his already maintained solution here into upstream and we close this one?

Saves us duplicate work.

@nefarius , no rush. I believe @atauenis meant something more comprehensive rather than this or what I've done. I think this "feature" will resolve itself within future releases. :)

[nefarius]

I can sure make it more sophisticated if desired 😜

[atauenis]

I've meaning this:

docker run -d -p 8080:8080 -v /your/local/webone.config:/home/webone --name CONTAINER_NAME IMAGE_NAME

And I'm not a professional user of Docker, don't know is it's possible with @nefarius dockerfile (don't see anything about unpack directory), probably impossible. This is a nice feature as sometimes it's useful to change some settings of WebOne.

The Dockerfile doesn't need to know the mount paths the user may or may not use, it can be annotated though. I'll add an example compose file to the PR later.

Me either :)
Though, I mean the new functionality in future would tell us what it must look like
It's really not necessary to push the docker build for now I believe. Everyone can make its own script that fits to the needs if desired or use mine or that you wrote. This doesn't matter for now.
@atauenis 's beautiful idea will show us the way ;)
